Our graphite electrode and electrode paste products have been exported to Europe, Asia, Africa, South America and Middle Eastern countries, which enjoys good reputation.

[Introducing Rongxing Electrode Paste]

The electrode paste from Rongxing Group is dehydrated and melted by petroleum coke and pitch coke in a melting tank, and proportionally added to the kneading pot and kneaded, then molded and calcined.

With the characteristics of low resistivity, it is used as a conductive material in electric furnace equipment such as ferroalloy furnace and calcium carbide furnace. Our electrode paste is said to be a technically complicated product in carbon production. After being kneaded and molded, our electrode paste became a finished product. Unlike other carbon products, when defects occur in the previous process, it can be compensated by baking, graphitization or even an impregnation process.

The electrode paste is calcined by the heat in the submerged arc furnace. The consumption speed of the electrode and the calcination speed are the key to the use of the electrode paste. As the submerged arc furnace technology gradually develops toward
large-scaled and air-tightness, during the calcining process, the electrode develops from the old type opened furnace type to the closed furnace type, and the heat obtained by the electrode from the furnace is greatly reduced, which requires an increase in the sintering perfromance of the electrode paste to compensate for this deficiency.

[Application of Rongxing Electrode Paste]

The Rongxing electrode paste is being used in the electric equipment such as ferroalloys furnace, carbide furnace as a conductive material.

[Points of Quality System of Rongxing Electrode Paste]

The company maintains stringent quality processes and standards in the industry to ensure an effective Quality Management System.

Holding itself to the high quality standards that control everything from incoming raw materials to final factory production.

All materials are tested to ensure they meet industry standards before entering the manufacturing phase.

Superior quality, outstanding customer service and operational dependability.

[Note for Rongxing-made Electrode Paste]

In addition to properly grasping the above two methods, the production of Rongxing electrode paste also needs to improve the sintering speed of the electrode through the adjustment of the formula, such as appropriately adding graphite materials with good conductivity and heat transfer performance in the formula Conduction heat obtained in the furnace to speed up the roasting speed, while trying to reduce the consumption of the electrode to reduce the speed of the electrode lowering can also achieve the matching of electrode consumption and roasting.
